Study Countdown

Hello! I’m reasonably new to GDevelop, and I’m wondering how it would be possible to create a countdown.
By this, I mean a way which allows one to input a time in minutes and seconds, and displays said input in a countdown!
I’ve searched around for quite a bit and have seen no answers that fit the bill for this exact thing, so any help is greatly appreciated ^^

Here’s a couple of examples which might be useful

Countdown Timer

Text Entry

You can use similar code but the amount of time shown on the countdown timer would be set according to a variable that gets updated after the user has done a text entry.
